Lesson 2 - States Of Matter Flashcards
The four fundamental states of matter that are observable in everyday life are?
Solid,liquid, gas,plasma
All matter is made up of ……….
Atoms
What is matter?
Matter is anything that has weight and takes up space
Give five examples of matter?
Water
Air
Smoke
Coke
Biscuit
What is an atom?
An atom is the smallest unit of matter.It is a particle million times smaller than dust. Which makes it impossible to see with the naked eye.
A……………………. Is a particle 1 million times smaller than a speck of dust.
An atom
It is possible to see an atom.
True / False
False
There are …………………… states of matter?
Four
Properties of solid
Solids cannot be easily compressed
They have a fixed shape and a fixed volume
When you drop a solid on the floor it doesn’t evaporate
Properties of liquid
Liquids take the shape of its container
They flow easily
They have indefinite shape
Liquids evaporate when they come in contact with heat
Properties of gas
The particles in a gas are very loosely packed
They can be easily compressed
They flow very easily
They have indefinite shape
Arrangements of particles in solid, liquid and gas
(List 3 each)
Solid:particles are tightly packed
Low kinetic energy
Don’t flow
Liquid:particles are closely packed
High kinetic energy
Flow
Gas:particles are loosely packed
Very high kinetic energy
Flow
Changing State of matter
1. Explain Evaporation
2. Condensation
3. Melting
4. Freezing
5. Sublimation
6. Deposition
7. Boiling
Evaporation: Evaporation is the stage where a liquid changes to gas when it comes in contact with very high temperatures.Eg.Water changes into vapor
Condensation: Condensation is when a gas is cooled and it turns into a liquid.
Melting: Is when a solid is heated and it turns into a liquid
Freezing: Is when a liquid cools and changes into a solid
